We know that we have passed from death to life because we love one another. Whoever does not love abides in death. All who hate a brother or sister are murderers, and you know that murderers do not have eternal life abiding in them. We know love by this, that [Jesus] laid down his life for us-and we ought to lay down our lives for one another. How does God's love abide in anyone who has the world's goods and sees a brother or sister in need and yet refuses help? Little children, let us love, not in word or speech, but in truth and action.
